Description

Packing container and package

The present invention relates to a packing container and a packing body for holding a plurality of glass plates stacked in a flat manner.

In recent years, there is an increasing need for large glass substrates used in FPDs and the like. As a packaging pallet for packaging such a large glass substrate, a packaging rack for fixing a glass substrate in a state in which a plurality of glass substrates are arranged upright as disclosed in Patent Document 1 is known.

However, since the packaging rack of Patent Document 1 is transported in a state in which the glass substrate is erected, when it becomes a large glass substrate, the airplane has a low (for example, 2 m or less) storage room or a conventional truck bed (for example, 2). .2m or less) could not be stored due to height restrictions. In addition, when transporting the glass substrate in an upright state, it is necessary to increase the size of one side of the bottom surface (for example, the height of the packaging pallet is 0) in order to secure stability such as preventing the packing pallet from falling. .5 times).
For this reason, the packaging rack of Patent Document 1 has a drawback that the transportation efficiency is poor because the volume and weight of the packaging rack increase as compared with the number of glass substrates to be loaded.

Against this background, Patent Document 2 discloses a pedestal, and a plate-like body mounting plate that is installed on the pedestal via a support member and a plurality of glass bodies are stacked substantially horizontally on the upper surface. A flat packing pallet having the following has been proposed. In this packing pallet, the upper surface of the plate-like body mounting plate is formed in a V-shaped cross section, so that the glass plate bent into a concave shape by flat stacking is stably held along the V-shaped bottom plate. I am doing so.
Patent Document 3 proposes a packaging container in which the placement surface of the glass plate is formed of a bendable sheet material, and the placement surface is curved around one axis.

Japanese Unexamined Patent Publication No. 2000-272684 International Publication No. 2008/105190 Japanese Unexamined Patent Publication No. 2010-13178

By the way, in Patent Document 2, the upper surface of the plate-shaped body mounting plate is formed in a V-shaped cross section, and in Patent Document 3, the mounting surface of the glass plate is curved around one axis, thereby making it concave by flat stacking. The bent glass plate is stably held. However, for example, when transported by a truck, if a force acts on the glass plate along the bending axis (central axis) in the V-shaped cross section or the length direction (axial direction) of the central axis in the curved surface, There is a possibility that the placed glass plate is displaced in the axial direction (lateral deviation). Therefore, there is a demand for a packaging form that prevents such a positional deviation of the glass plate and that can hold and fix the glass plate more stably.

The present invention has been made based on such a background, and prevents a positional deviation of a flat glass plate during transportation and the like so that the glass plate can be held and fixed more stably. The purpose is to provide a body.

The packaging container of the present invention is a packaging container that holds and holds a glass plate in a substantially horizontal state,
A pedestal and a mounting plate having a rectangular shape in plan view arranged on the pedestal and mounting a glass plate, and the mounting plate described above has all four corners curved toward the center, At least two corners are independently curved toward the center.

Moreover, the said packaging container WHEREIN: As for the said mounting plate, the four corners may each curve toward the center part independently.
Further, in the packing container, the mounting plate is configured such that one side including the two adjacent corners is curved toward the center, and the other two corners are independently curved toward the center. You may do it.
Moreover, it is preferable that the above-mentioned mounting plate is formed in the substantially same magnitude | size as the glass plate to mount.

The packing body of the present invention includes the packing container and a plurality of glass plates that are stacked and held flat on the mounting plate described above.

According to the packaging container of the present invention, the mounting plate on which the glass plate is placed has all four corners curved toward the center, and at least two corners independently curved toward the center. Therefore, the plurality of glass plates that are stacked and held flat on the mounting plate have a long side direction and a short side direction, particularly by two corners that are curved independently toward the center. Movement is restricted. Thereby, the movement, that is, the lateral displacement (positional displacement) is restricted with respect to all directions in the surface direction. Therefore, the glass plate can be held and fixed more stably during transportation or the like.
According to the packaging body of the present invention, the packaging body and the plurality of glass plates stacked and held flat on the mounting plate described above on the packaging container are more stable during transportation. Thus, the glass plate is held and fixed.

FIG. 1 is a perspective view showing an appearance of an embodiment of a packaging body of the present invention. FIG. 2 is an exploded perspective view for explaining a schematic configuration of the package shown in FIG. 1. FIG. 3 is a cross-sectional view of the package shown in FIG. 4 (a) and 4 (b) are side sectional views showing the configuration of the vibration absorbing member. FIG. 5 is a plan view of the tray. 6 is a perspective view showing a mounting plate of the packaging container shown in FIG. 7A is a conceptual diagram of the shape of the mounting plate of the packaging container shown in FIG. 1, FIG. 7B is a conceptual diagram of the shape of the mounting plate as another embodiment, and FIG. ) To 7 (e) are conceptual diagrams of the shape of the mounting plate of the reference example. FIG. 8 is an explanatory diagram of the slip sheet pressing member.

Hereinafter, although one embodiment of the packing method and packing body of the present invention is described, the present invention is not limited to the embodiment described below.
FIG. 1 is a perspective view showing an external appearance of a glass plate packaging body 1 according to the present embodiment. FIG. 2 is a schematic view of a packaging body 1 in which a plurality of glass plates G are stacked and held on a packaging container 10. It is a disassembled perspective view for demonstrating a structure.

In the packing container 10, a plurality of (for example, 80 to 150) rectangular glass plates G are stacked in a substantially horizontal manner and stored. Further, between the glass plates G, a slip sheet 12 having a larger area than the glass plate G and formed in a rectangular shape is sandwiched. The glass plate G shown in the present embodiment is a thin large glass substrate used for FPD, and has a thickness of 0.5 mm to 2.8 mm, for example, and a vertical and horizontal size of about 2400 mm × 2100 mm to 3200 mm × 3000 mm. This is a large glass plate.

Further, as the slip sheet 12, the smoothness of the paper (JIS P 8119, 1976) is used to prevent the resin content in the slip sheet 12 from being transferred to the surface of the glass plate G and causing a paper texture pattern, burns or dirt. Is a roughened surface of 20 seconds or less, preferably 18 seconds or less. Thereby, the contact area with respect to the surface of the glass plate G reduces, and the transfer of a resin part is suppressed. In addition, the resin content is adjusted to 0.1% by mass or less, preferably 0.05% by mass or less (JIS P 8205, 1976), thereby maintaining the quality of the glass plate G by the combined action with the rough surface. A possible slip sheet 12 is preferred.

As shown in FIG. 2, the packaging container 10 includes a pedestal 14 and a placement plate 16 that are rectangular in a plan view, and a slip sheet pressing member 18. In addition, guide members 20 constituting the container stacking means are respectively provided upright at the four corners of the packing container 10. Thereby, when packing containers 10 are stacked in a plurality of stages in the vertical direction and transported, the packing containers 10 can be easily positioned, and the packing containers 10 can be fixed.

As shown in FIG. 3, which is a cross-sectional view taken along line AA in FIG. The steel material 22 is formed of, for example, an extruded material made of an aluminum alloy or a steel plate cut into a predetermined shape. Then, at least two pieces in which the steel materials 22 are assembled in a lattice shape in the vertical and horizontal directions are manufactured, and these are connected by the steel material 22 so that the lattice planes are substantially parallel to form the base 14. The steel material 22 may be any metal, resin, or the like as long as it is rigid and does not generate particles, but aluminum or an aluminum alloy is preferable in terms of weight, rigidity, and cost.

As shown in FIGS. 1 and 2, forklift openings 28 into which forks of a forklift (not shown) are inserted are formed at two positions on one side of the base 14. As a result, the fork of the forklift can be inserted into the packing container 10 from any of the vertical and horizontal side surfaces of the pedestal 14 so that the work can be performed efficiently.

As shown in FIG. 3, the mounting plate 16 is mounted on the pedestal 14 via a vibration absorbing member 30, an inclination angle setting member 32, and the like.
The vibration absorbing member 30 includes a large number of shrinkage absorbing members 34 and extension absorbing members 36, and is disposed between the pedestal 14 and a tray 38 provided with the inclination angle setting member 32, and is mounted from the pedestal 14. The vibration transmitted to the mounting plate 16 is absorbed.

As shown in FIG. 4A, the shrinkage absorbing material 34 includes a gel material 40 having elasticity, and concave brackets 44, 44 are provided on the upper and lower ends of the gel material 40 via metal plates 42, respectively. It is fixed by bolts 46, 46. The lower bracket 44 is fixed to the pedestal 14 with screws 48, and the upper bracket 44 is fixed to the tray 38 with screws 48, whereby the shrinkage absorber 34 is fixed between the pedestal 14 and the tray 38. ing.

As shown in FIG. 4B, the stretch absorbent material 36 includes a gel material 50 having elasticity, and a substantially U-shaped bracket 52 is fixed to the upper end of the gel material 50 by a pin 54. The lower end of the bracket 52 is fixed to the pedestal 14 with a pin 56. A substantially U-shaped bracket 58 is arranged below the gel material 50 with a predetermined gap, and the upper end of the bracket 58 is fixed to the receiving tray 38 by a pin 59. It is fixed between the saucer 38.

As shown in FIG. 3, the shrinkage absorbent 34 and the stretch absorbent 36 are regularly (eg, alternately) disposed on substantially the entire bottom surface of the tray 38. As a result, the vibration in the vertical direction accompanying the shaking of the pedestal 14 due to the vibration during transportation is absorbed, and this vibration is not transmitted to the mounting plate 16 on the pedestal 14 via the tray 38. That is, when the space between the tray 38 and the pedestal 14 is compressed (in the direction of arrow F1 in FIG. 4A), the gel material 40 constituting the shrinkage absorbing material 34 is compressed and contracted, so that the direction of the arrow F1 is reduced. Vibration is absorbed well. When the space between the tray 38 and the pedestal 14 is extended (in the direction of arrow F2 in FIG. 4B), the gel material 50 constituting the extended absorbent material 36 is compressed and contracted by the bracket 52 and the bracket 58. Thus, the vibration in the direction of the arrow F2 is well absorbed. In either case, the gel materials 40, 50 themselves absorb vibration when compressed. Therefore, problems such as positional deviation of the glass plate G caused by vibration transmitted from the pedestal 14 to the mounting plate 16 via the tray 38 are prevented.

The gel materials 40 and 50 are preferably materials that can efficiently absorb, for example, a vibration frequency of 8 to 20 Hz in consideration of the natural frequency generated in a vehicle or an airplane during land transportation or air transportation. For example, a vibration absorbing material such as rubber, resin, or silicone can be used. Further, instead of the gel materials 40 and 50, an elastic body such as compression rubber or a metal compression spring may be used. Furthermore, an elastic body having an elastic action against tension can be used.

The saucer 38 includes a saucer frame 39 and an inclination angle setting member 32 as shown in FIGS. The tray frame 39 is formed in a lattice shape by assembling vertically and horizontally a plurality of steel materials 61 formed by, for example, extruding a material made of an aluminum alloy or a steel plate cut into a predetermined shape. The inclination angle setting member 32 is constituted by a plurality of steel materials (support members) 60 having different heights fixed on the tray frame 39.

As shown in FIG. 5, which is a plan view of the tray 38 in the present embodiment, the steel members 60 are arranged at the four corners, that is, at the respective corners corresponding to the four corners of the mounting plate 16 having a rectangular shape in plan view. It has the steel material 60a and the other steel materials 60b arrange | positioned other than these four corner parts. The steel material 60a arranged at each corner is formed to have a predetermined height, for example, about 10 mm to 50 mm higher than the other steel materials 60b. The predetermined height is appropriately determined depending on the size of the glass plate G stacked and held on the packaging container 10. In the present embodiment, the other steel members 60b are disposed between the steel members 60a and 60a, and a plurality (three in FIG. 5) are disposed along the long side direction of the tray frame 39. However, the number and arrangement of these other steel materials 60b can be changed as appropriate.

Further, the steel material 60a disposed at each corner is not particularly limited, but it is preferable that the upper end surface of the steel material 60a is inclined downward toward the center of the tray frame 39. By forming in this way, when the mounting plate 16 is affixed on the steel materials 60a and 60b as will be described later, the four corners gently curve toward the center. Here, in the present invention, the center portion does not necessarily mean the center point of the tray frame 39 or the mounting plate 16, but means a relatively wide range including the center point and the vicinity thereof. For example, the direction of the central portion where the upper end surface of the steel material 60a is inclined is the perpendicular S direction of the rhombus H indicated by a two-dot chain line in FIG. In addition, the rhombus H in FIG. 5 is formed by connecting the center points of the respective sides of the tray frame 39 having a rectangular shape in plan view.

On these steel materials 60 (60a, 60b), as shown in FIG. 6, a mounting plate 16 made of an aluminum plate or the like and having the same size and shape as the glass plate G to be laminated and held is pasted. . This mounting plate 16 is mounted on each steel material 60 (60a, 60b), and is curved by its own weight from each corner to the center by supporting the four corners at a high position. The steel material 60 (60a, 60b) is adhered and pasted with a double-sided adhesive tape or the like. Specifically, the mounting plate 16 is attached to the steel material 60a at each corner shown in FIG. 5 and the steel material 60b in the rhombus H by adhesion or the like. Thereby, as shown in FIG. 6, as for the mounting board 16, all four corners are curving toward the center part.

That is, although the mounting plate 16 becomes a plane (substantially horizontal plane) by being attached to the steel material 60b having the same height in the rhombus H, the steel material 60a is formed between the steel material 60a and the rhombus H at each corner. And the steel material 60b are inclined based on the height difference and further curved so as to protrude downward due to its own weight. In other words, the mounting plate 16 has its four corners (corners) curved independently toward the center. Accordingly, the mounting plate 16 is formed with independent curved portions 16a at the four corners (corner portions).

Here, the center portion does not mean the center point of the mounting plate 16 as described above, but means a relatively wide range including the center point and the vicinity thereof. For example, a two-dot chain line in FIG. The extension line of the perpendicular line S shown by means the part closest to the center point. However, of course, the central portion may coincide with the central point in design.
In addition, if each corner part of the mounting plate 16 is curved in this way, an appropriate support material may be interposed between each curved part 16a and the steel material 60b or the tray frame 39 for reinforcement.

The height difference of each curved portion 16a of the mounting plate 16 is determined by the height difference of the steel materials 60a and 60b of the inclination angle setting member 32, and is thus about 10 mm to 50 mm as described above. By setting it as 10 mm or more, the position shift (lateral shift) of the glass plate G mounted on the mounting plate 16 can be prevented more favorably as described later. In addition, when the glass plate G is loaded or unloaded, the corners of the stacked glass plates G interfere with a loading or unloading robot arm (not shown) or the like when the glass plate G is loaded or unloaded. Can be avoided.

Note that such a height difference (10 mm to 50 mm) of each curved portion 16a is converted to an inclination angle at the perpendicular S in FIG. 5, for example, 0.7 ° to 3.5 for a G8 size (2200 mm × 2500 mm). In addition, in the G10 size (2880 mm × 3130 mm), it is about 0.5 ° to 2.7 °. Therefore, in practice, it is such a degree that it does not appear to be almost curved (inclined).

The mounting plate 16 may be any material and thickness that can be easily elastically deformed by following the height difference between the steel materials 60a and 60b, and further curved so as to protrude downward due to its own weight. In addition, various materials such as an aluminum alloy plate and an aluminum honeycomb plate can be used.

FIG. 7A is a conceptual diagram of the shape of the mounting plate 16 of the packaging container 10 shown in FIG. 1. As shown in this figure, the mounting plate 16 has the curved portions 16a independently at the four corners. Forming. Thereby, the mounting plate 16 has a curved axis T for each corner (curved portion 16a) as shown by a broken line in FIG. Therefore, the mounting plate 16 regulates the movement, that is, the lateral displacement (positional displacement) of the glass plate G laminated and held thereon with respect to all directions in the surface direction. That is, since the glass plate G has substantially the same size and shape as the mounting plate 16, the glass plate G intersects with the bending axis T of the bending portion 16 a regardless of the surface direction. Therefore, the movement is restricted by interference with any one of these curved portions 16a.

In addition, the mounting board of this invention is not limited to the structure shown to Fig.7 (a), For example, the structure shown to FIG.7 (b) can also be taken. That is, in the mounting plate 16 shown in FIG. 7A, the four corners are independently curved toward the central portion, whereas in the mounting plate 17 shown in FIG. The entire side including the two corners is curved toward the center to form the curved portion 17b, and the other two corners are independently curved toward the center to form the curved portion 17a. ing.

The curved portion 17a that is curved at the corner has the same configuration as the curved portion 16a in the mounting plate 16 shown in FIG. Further, the curved portion 17 b is curved toward the center line in the longitudinal direction of the long side of the mounting plate 17. Therefore, both corners constituting the curved portion 17b are curved toward the center portion of the mounting plate 17 by being curved toward the center line direction.

The mounting plate 17 having such a configuration has a bending axis T for each of the bending portions 17a and 17b, as indicated by a broken line in FIG. 7B. Therefore, the mounting plate 17 also regulates the movement, that is, the lateral displacement (positional displacement) of the glass plate G laminated and held thereon with respect to all directions in the surface direction. In other words, the glass plate G intersects the bending axis T of the bending portions 17a and 17b regardless of the direction in which the glass plate G moves. And by interfering with the curved portion 17a that is curved toward the central portion independently, movement in the short side direction of the glass plate G and the direction toward the curved portion 17a is regulated. Yes. Further, movement in the direction toward the bending portion 17b is also restricted by interference with the bending portion 17b.

Accordingly, the movement of the glass plate G is restricted by interference with either of the curved portions 17a and 17b.
About the mounting board 17 which has such curved parts 17a and 17b, the steel material 60b arrange | positioned between the corners in one short side part is the same as the steel material 60a in a corner among the steel materials 60b shown in FIG. It can be formed by increasing the height.

In addition, as a structure of a mounting board, what is shown to FIG.7 (c)-(e) can also be considered as a reference example. The mounting plate shown in FIG. 7C has curved portions 17b formed on opposite sides. However, in this mounting plate, although it is possible to satisfactorily prevent the positional deviation of the glass plate G with respect to the arrow X direction in FIG. Cannot prevent the positional deviation as in the conventional case.

In addition, the mounting plate shown in FIG. 7 (d) forms the curved portion 17a only for a pair of corners opposed on one diagonal, but for a pair of corners opposed on the other diagonal, A planar shape is formed without forming a curved portion. However, in this mounting plate, it is possible to prevent the positional deviation of the glass plate G with respect to one diagonal direction, that is, the arrow X direction in FIG. 7D, but it is the other diagonal direction. For the arrow Y direction, it is not possible to prevent the displacement.

In addition, the mounting plate shown in FIG. 7E has a curved portion 17b formed on one side and a curved portion 17a formed only on one of the other corners. However, this mounting plate cannot prevent the positional deviation of the glass plate G with respect to the other corner, that is, the direction of the arrow Y in FIG.
Therefore, as the mounting plate in the packaging container 10 and the packaging body 1 of the present invention, as shown in FIG. 7A or 7B, the bending axis T corresponding to each bending portion extends in all directions. Those configured to be closed are employed.

As shown in FIG. 2, a resin sheet 62 for buffering vibrations generated by conveyance or the like is attached to the mounting plate 16 having such a configuration. The material of the resin sheet 62 is not particularly limited, but it can follow the surface shape of the mounting plate 16 (17) serving as the base, and can form the same curved shape as the curved portions 16a (17a, 17b). The ones with properties are used. A material having such thickness and properties, excellent cushioning properties, good workability, little thermal deformation, and no degassing affecting the glass is preferably used. A large number of glass plates G are laminated on the resin sheet 62 with the interleaf paper 12 interposed therebetween.

The laminated glass plate G has a very thin thickness of, for example, about 0.5 mm to 2.8 mm. Therefore, the glass plate G bends in accordance with the surface shape of the mounting plate 16, that is, the surface shape of the resin sheet 62. All the parts are curved toward the center.
In addition, the slip sheet 12 is laminated so that a substantially predetermined amount of the slip sheet 12 protrudes from each side of the glass sheet G by aligning the approximate center of the slip sheet 12 and the glass sheet G in the planar direction. At that time, on the glass plate G, like the glass plate G, all four corners are curved toward the center.

As shown in FIG. 1, for example, two slip sheet pressing members 18 are arranged at predetermined intervals on each of the four sides of the tray 38, and are fixed to the tray 38 with screws 64 and 64. When the slip sheet pressing member 18 is fastened by the screw 64, the glass sheet G is pressed from the side by the slip sheet pressing member 18. As a result, the glass plate G is sandwiched by the interleaf sheet pressing members 18 on its four sides. Further, the slip sheet 12 protruding from the four sides of the glass plate G is fixed to the mounting plate 16 by being pressed by the slip sheet pressing member 18 as shown in FIG.

In this embodiment, two slip sheet pressing members 18 are arranged on each side of the tray 38, but the present invention is not limited to this, and each side of the tray 38 corresponds to the length of each side. Only one piece may be provided, or three or more short slip sheet pressing members may be provided along each side.

Also, the slip sheet pressing member 18 presses the slip sheet 12 that protrudes from the side surface of the glass plate G and hangs downward as shown in FIG. At this time, the overlapped end portion of the slip sheet 12 is pressed by the slip sheet pressing member 18, so that the slip sheet pressing member 18 does not directly contact the side surface of the glass plate G. Therefore, while the glass plate G is protected by the flexibility of the interleaving paper 12, the side surfaces of the four sides of the laminated body of the glass plates G are surely pressed. Further, even if the glass plate G tries to move up and down due to vibration, the interleaving slip sheet 12 is sandwiched between the slip sheet pressing member 18 and the side surface of the glass plate G, so that the slip sheet 12 is attached to the mounting plate 16 Therefore, the vertical movement of the glass plate G can be suppressed. In addition, the lateral displacement of the glass plate G can be prevented.

Incidentally, the slip sheet pressing surface 19 of the slip sheet pressing member 18 is formed with an inclined surface in a direction away from the glass plate G from the upper part toward the lower part according to the thickness of the overlapping slip sheets 12. As a result, the slip sheet 12 can be reliably pressed by the slip sheet pressing member 18, and the pressing force applied to the end sides of the glass plates G stacked via the slip sheet 12 can be equalized. Therefore, there is no possibility that an excessive load is applied to the glass plate G and the glass plate G is damaged.

According to the packaging container 10 of this embodiment, since it presupposes that the glass plate G is conveyed in the state of being horizontally stacked, compared with the conventional vertical transfer mode, the transfer means Sufficient loading efficiency can be provided, and even a hangar with a low ceiling such as an airplane or a truck can be easily stored as compared with a vertical transfer type.

Further, the mounting plate 16 (17) of the packaging container 10 has all four corners curved toward the center, and at least two corners independently curved toward the center. Since 16a (17a, 17b) is formed, the plurality of glass plates G stacked and held flat on the mounting plate 16 (17) are curved independently toward the center. The movement in the long side direction and the short side direction can be restricted by the two corners. Thereby, the movement, that is, lateral deviation (positional deviation) can be regulated with respect to all directions in the surface direction. Therefore, the glass plate G can be held and fixed more stably during transportation or the like.
The packaging container 10 can be reused as it is after the glass sheet G is packed and transported, unpacked and the glass sheet G is taken out. Such reuse can be repeated many times.

Moreover, according to the package 1 of this embodiment, the said packaging container 10 and the several glass plate G laminated | stacked and hold | maintained flatly on the mounting board 16 (17) of this packaging container are provided. Therefore, the glass plate G is more stably held and fixed during transportation.

The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the gist of the present invention.
For example, in the above embodiment, an aluminum plate material having high rigidity and light weight is used as the mounting plate 16 (17), but this may be an aluminum honeycomb plate.
Moreover, in the said embodiment, although the interleaving paper 12 was interposed between the glass plates G, a plurality of glass plates G may be directly laminated in a flat stack without interposing the interleaving paper 12 in this way. .

Although the present invention has been described in detail and with reference to specific embodiments, it will be apparent to those skilled in the art that various modifications and variations can be made without departing from the scope and spirit of the invention.
